TORONTO -- Kevin Gausman arrived in the visiting clubhouse of the Rogers Centre on Thursday to find about $300 worth of powdered mini doughnuts stacked inside and at the base of his locker, another nice welcoming gift from center fielder Adam Jones.

The 22-year-old Gausman will make his major league debut tonight against the Blue Jays. Gausman -- who was known for eating doughnuts between innings at LSU -- apparently needed to go back to his apartment near Bowie to get his passport before joining the club.

And unlike his arrival in Baltimore on Wednesday – when cameras and recorders crowded his locker and watched his every move – there was no hoopla when travel secretary Kevin Buck presented Gausman with his contract to sign and officially become a major leaguer.

To make room for Gausman on the 25-man roster, the Orioles optioned right-hander Jake Arrieta to Triple-A Norfolk. He will jump back into the starting rotation there. The team designated right-hander reliever Alex Burnett for assignment to make room on the organization’s 40-man roster.

Jones, who is dealing with a sore groin, is in the DH spot for the third straight game. Jones said he’s confident he will be back in center field Friday. Showalter said he wants to be careful with Jones on the artificial turf here in Toronto.

Wilson Betemit (Grade 2/3 PCL tear) saw team doctors in Baltimore and has been cleared to begin light baseball activities next week. Catcher Taylor Teagarden (left thumb) caught live batting practice and took BP swings against coaches on Thursday in Sarasota, Fla.
